12 Ss classified 24 random forms successively into two arbitrary subsets in each of 3 trial-blocks. 24 polygons used were randomly selected from two stimulus groups which were derived from two different prototypes by a probabilistic operation using a double Markov matrix. The major purpose of the experiment was to make clear whether or not the subsets divided by Ss match the E-defined subset and how to utilize cue dimensions in the physical measurement space for classifing the stimuli. The results were as follows; (1) None of Ss was unable to reach the criterion by which the obtained subsets were statistically judged whether they match the E-defined subset. (2) Compactness was identified as the most important cue dimension. (3) The notion of similarity classification (SC) and dimensional classification (DC) proposed by Handel & Imai (1972), was used to find what kind of strategy should be taken for producing subsets. DC was employed in more blocks and in more Ss than SC.
